OPERATION UNIT 82

[0055] The operation unit 82 is for example a mouse, keyboard, or remote controller and is used by the user for instructing whether or not to display an image corresponding to the additional signal or indicating the format of the related display etc.

[0056] Below, an explanation will be made of an example of the operation of the broadcast system 61.

[0057]FIG. 2 is a flowchart for explaining an example of operation of the broadcast system 61 shown in FIG. 1.

Step ST1

[0058] The broadcast apparatus 60 generates a broadcast signal S60 comprised of a mix of a program signal PS and an additional signal AS and broadcasts the related broadcast signal S60 to the receiving apparatus 70 on the user side by a wired or wireless method.

Step ST2

[0059] The broadcast signal S60 is received at the receiver 71 of the receiving apparatus 70, processed for demodulation, decoding, error correction, etc. at the receiver 71, and then output to the filter 72.

Step ST3

[0060] The filter 72 of the receiving apparatus 70 separates the program signal PS and the additional signal AS mixed in the broadcast signal S60.

Step ST4

[0061] The program signal PS separated at step ST3 is written into the program signal use memory 73, while the separated additional signal AS is written into the additional signal use memory 74.

Step ST5

[0062] When an instruction indicating to display an image corresponding to the additional signal AS is output by the operation unit 82, the processing of step ST6 is executed, while the processing of step ST7 is executed in other cases.

Step ST6

[0063] Under the control of the controller 77 of the receiving apparatus 70, the program signal PS read from the program signal use memory 73 and the additional signal AS read from the additional signal use memory 74 are written into the video RAM 75 as the output use image signals.

[0064] Then, the display 76 displays an image in accordance with the program signal PS and an image in accordance with the additional signal AS.

Step ST7

[0065] Under the control of the controller 77 of the receiving apparatus 70, the program signal PS read from the program signal use memory 73 is written into the video RAM 75 as the output use image signal.

[0066] Then, the display 76 displays an image corresponding to the program signal PS, but does not display an image corresponding to the additional signal AS.

Step ST8

[0067] The log information generator 81 generates log information indicating a log of the display instructions of images corresponding to the additional signal by the user based on the operation signal from the operation unit 82 and the control log information from the controller 77 and transmits the related log information from the transmitter 80 to the broadcast apparatus 60.

[0068] Then, the broadcast apparatus 60 charges the related user based on the log information received from the transmitter 80 on the user side.

[0069] As explained above, according to the broadcast system 61, whether or not to display an image corresponding to the additional signal AS contained in the broadcast signal S60 on the display 76 can be determined by the user on the reception side. Namely, the display format of the image corresponding to the broadcast signal S60 can be determined on the reception side matching the preference of the user. For this reason, a service attractive to the user can be provided. Also, the broadcast station can provide a variety of services to the user by using an additional signal AS other than a broadcast of the program, so it becomes possible to link up a program broadcast and various businesses.

[0070] Also, according to the broadcast system 61, by reflecting the display of an image corresponding an additional signal AS by a user in the sum charged for the program service, utilization of a related service by the user can be promoted and new businesses other than the program broadcast can be created.

[0071] While the invention has been described with reference to a specific embodiment chosen for purpose of illustration, it should be apparent that numerous modifications could be made thereto by those skilled in the art without departing from the basic concept and scope of the invention.

[0072] For example, in the above embodiment, in the receiving apparatus 70 shown in FIG. 1, the case where the display of an image corresponding to the additional signal AS was selected after receiving the additional signal AS was exemplified, but it is also possible to transmit a request specifying the additional signal AS intended by the user from the transmitter 80 to the broadcast apparatus 60 in accordance with the operation of the operation unit 82 by the user and transmit an additional signal AS corresponding to the related request to the receiving apparatus 70 by the broadcast apparatus 60.

[0073] Also, in the above embodiment, the case where a broadcast signal S60 containing a program signal PS and an additional signal AS was transmitted to the receiving apparatus 70 by using the broadcast apparatus 60 was exemplified, but the present invention can also be applied to a case where for example a server connected to a network such as the Internet is used in place of the broadcast apparatus 60, and the related server provides picture and sound information to the receiving apparatus 70 in accordance with the request from the receiving apparatus 70.

[0074] Also, in the above embodiment, it is also possible to perform the charge processing by the broadcast apparatus 60 in accordance with the display of the additional signal on the user side based on for example a viewing agreement made in advance or two-way between the transmitter 80 and the receiving apparatus 70 and the broadcast apparatus 60.
